Hi all,

Apologies if this is in the wrong section, but i need help asap. :confused::confused:

New to the PC Building ventures, so i've built my pc (specs listed below) but i am having problems with my CPU usage in task manager it

just goes sky high. This occurs, when i'm using any interner browser (chrome, ie...) watching youtube or any video, or just randomly

any windows services will hit 60-95% and drop. Fan just runs and makes a constant semi-loud noise.

I have attacehd a picture, when windows was installing updates and at random times hit 98-100% for 10 seconds and then dropped

instantaneously.

Initally i installed Windows 8.1 and had the problem, now i've down a clean install of windows 7 and i'm having same problem.

I read online that removing the cpu fan and putting it back on would do the trick, not realizing after i had done that the thermal

paste may get messed up. What shall i do??? Should i remove once again and clean up and re-apply thermal paste?

Yes, i have all drivers installed and up to date.

I have no idea what is causing this problem, on average what should the average cpu usage be?

Looks like it's all down to your .Net runtime optimisation service. Just let it run, and it will eventually sort out optimising all your .Net stuff. It just takes time and runs at a low priority.

Alternatively read this. It will tell you how to force the .Net optimisation to run at high priority and finish quickly.

Short version:

mscorsvw.exe is precompiling .NET assemblies in the background. Once it's done, it will go away. Typically, after you install the .NET Redist, it will be done with the high priority assemblies in 5 to 10 minutes and then will wait until your computer is idle to process the low priority assemblies. Once it does that it will shutdown and you won't see mscorsvw.exe. One important thing is that while you may see 100% CPU usage, the compilation happens in a process with low priority, so it tries not to steal the CPU for other stuff you are doing. Once everything is compiled, assemblies will now be able to share pages across different processes and warm start up will be typically much faster, so we're not throwing away your cycles.
If you are really want to get rid of mscorsvw.exe from your task manager, just do:

ngen.exe executequeueditems

which will drain all the queued up work.

If you have installed your cooler, and then removed it, you should ideally take it off, clean up the paste and reapply. If you take a cooler off and put it back on with out cleaning/reapplying the paste, you're likely to get air bubbles in the paste that won't transmit heat very well.

In your position, I would fix the .Net stuff first, then see what your temps are like as to whether you think it's worth re-doing the cooler and paste.

When did you re install windows? There are a LOT of windows updates to be d/l installed and usually requires multiple restarts when doing clean install.

Windows also has a habit for doing it without making it clear to you thats what its doing.

No need to mess about with and reinstall your cooler.That wont get you anywhere with this problem.
 
I followed the guide given above, windows updates as regularly. Also i have re-applied new thermal paste. But still i have problems.

Click on "show processes from all users" and see what it clocking up CPU time.

If that doesn't show the process, then run the resource monitor and look at the CPU processes. On a new install I wouldn't be surprised if it's not the search indexer, compounded by the Kaspersky you have installed checking every file it accesses. In that case, just let it run and it will sort itself out.

You need to identify the processes that are taking the CPU time, it's no use looking at a task manager window that is full of zero CPU.
